Draw salves, also known as drawing ointments or black salves, are topical preparations that are traditionally used to treat skin conditions such as boils, splinters, and other types of skin infections or irritations. The name "draw" salve comes from the belief that the ointment can "draw out" the infection or irritant from the skin.

The active ingredients in most draw salves are typically a combination of herbs and other botanical ingredients that have astringent, anti-inflammatory, and antimicrobial properties. Some common ingredients found in draw salves include calendula, comfrey, echinacea, and tea tree oil.

Draw salves are typically applied directly to the affected area of the skin and left in place for a certain period of time, usually several hours. The ointment may be covered with a bandage or left uncovered, depending on the specific instructions provided by the manufacturer or the healthcare provider.

It's important to note that while draw salves can be effective for certain types of skin conditions, they should not be used on large or deep wounds, or on any open sores or puncture wounds. They should also not be used on or around the eyes. If you are unsure whether a draw salve is appropriate for your condition, or if your condition does not improve after using a draw salve, it is important to consult a healthcare professional for further advice.

Also it's important to note that the use of draw salves that contain the plant extract bloodroot (Sanguinaria canadensis) is controversial. Extracts of the plant have been used in traditional medicine, but it's efficacy and safety is not established. The American Cancer Society recommends against using these salves because they can cause serious side effects, including severe inflammation, scarring, and even cancer.
